Obama Warns of New Threats From Syrian Conflict

President Barack Obama said that the conflicts in Syria and Iraq could pose dangers for homeland security, because militants carrying European passports might be able to gain entry to the United States.

The U.S. needs to improve intelligence, reconnaissance, and surveillance in order to minimize new risks, said Mr. Obama in an interview that aired Sunday on ABC’s “This Week.”

“We have seen Europeans who are sympathetic to their cause traveling into Syria and now may travel into Iraq, getting battle-hardened,” said Mr. Obama. “Then they come back. They’ve got European passports. They don’t need a visa to get into the United States.”
